Packman: Procedures to follow when using Stretch Wrap | Singapore
When using stretch wrap (also known as stretch film), it’s important to follow proper procedures to ensure the wrapping process is efficient, secure, and safe. Stretch wrap is commonly used for packaging items on pallets, securing goods for transportation, or bundling products together. Below are the key procedures to follow when using stretch wrap:
1. Choose the Right Type of Stretch Wrap
- Pre-stretched vs. Hand Stretch Wrap: Choose the appropriate type of stretch wrap based on the size, weight, and fragility of the items being wrapped. Pre-stretched wrap is ideal for heavy-duty use, while hand stretch wrap is suitable for lighter items or smaller packaging.
- Thickness and Width: Select the correct gauge (thickness) and width of the stretch wrap to suit your packaging needs. Thicker wrap provides more security, while thinner wrap is more flexible and lighter.
- Blown vs. Cast Stretch Wrap: Blown wrap offers higher stretch and puncture resistance, while cast wrap is quieter and has better clarity.
2. Prepare the Items to Be Wrapped
- Clean and Organize: Ensure that the items or products to be wrapped are clean, free from debris, and properly organised on the pallet or in the wrapping area.
- Stack Items Securely: Arrange the items in a stable and uniform manner. If you’re wrapping a pallet, ensure that the products are evenly stacked to maintain balance and prevent tipping during transport.
3. Position the Stretch Wrap Roll
- Mounting the Roll: For manual wrapping, place the stretch wrap roll on a dispenser, which should be positioned at an accessible height for efficient wrapping. For automated systems, ensure the machine is set up correctly according to manufacturer instructions.
- Check for Tangles: Make sure the stretch wrap roll is free from tangles or twists before starting the wrapping process to avoid delays or uneven wrapping.
4. Start Wrapping
- Anchor the Film: Start by anchoring the beginning of the stretch film to the bottom of the stack or pallet. This can be done by stretching a small portion of the wrap over the load and pressing it onto itself to create an initial bond.
- Wrap in Layers: Begin wrapping around the pallet in horizontal or vertical layers, ensuring the stretch film covers the entire load. Overlap each layer by at least 50% for added security.
- Maintain Tension: Maintain a steady tension while wrapping to ensure the film stretches evenly. A consistent pull ensures the wrap is tight, which holds the items securely. Avoid too much tension, as it could cause the wrap to tear or break.
- Avoid Excessive Wrapping: Don’t overwrap the items. Aim for a balance, wrapping the pallet enough to secure it but not excessively wrapping it, which can lead to wasted film and unnecessary weight.
5. Secure the Top and Bottom of the Load
- Top Layer: Once you reach the top of the load, continue wrapping over the top to secure the final layers in place. This prevents the film from loosening during transportation.
- Bottom Layer: When starting the wrap, be sure to secure the bottom layers tightly as well. This ensures that the items will not shift during transport. Wrap around the base multiple times to create a stable foundation.
6. Finish the Wrap
- Cut and Secure the Film: After the load is fully wrapped, cut the stretch wrap and use the tail of the film to seal the final layers. If using a manual dispenser, simply cut the film and press the end of the wrap against the load to secure it.
- Ensure No Loose Ends: Check that there are no loose ends or sections where the wrap could unravel. Properly secure the end of the wrap by pressing it against the pallet or load.
- Check for Stability: After finishing the wrap, gently test the stability of the wrapped load by attempting to move it or lift it (if possible). If it’s unstable, apply additional layers of stretch wrap as needed.
7. Inspect the Wrapped Load
- Check for Proper Tension: Ensure the stretch wrap is taut around the load and that it is securely wrapped with no gaps.
- Ensure Full Coverage: Confirm that the entire load is covered, including the sides and top. Any exposed parts could lead to damage or instability during transportation.
- Inspect for Tears: Examine the wrap for any tears or punctures, especially in high-stress areas. If any issues are found, rewrap or apply additional layers.
8. Transport and Storage
- Handle With Care: Once wrapped, handle the pallet or load carefully. Stretch wrap helps secure the items, but it’s still essential to move the load cautiously to avoid any unexpected shifting or damage.
- Storage: Store wrapped items in an environment where they won’t be exposed to extreme heat, moisture, or excessive stress. While stretch wrap is designed to protect items, ensure the storage area is suitable for the type of goods you’re securing.
9. Disposal and Recycling
- Recycling: After use, dispose of the stretch wrap properly by recycling it if possible. Stretch film is made from plastic, which may be recyclable in certain areas. Check with your local recycling facility for guidance.
- Avoid Landfill Disposal: To minimise environmental impact, try not to dispose of stretch wrap in regular trash or landfills, as it is not biodegradable.
By following these procedures when using stretch wrap, you ensure that your items are securely packaged and protected for transport or storage. Proper tension, consistent layers, and ensuring that both the top and bottom of the load are secured are key steps in achieving an effective wrap. Additionally, always dispose of used stretch wrap responsibly to minimise environmental impact.
